You realise why all this is happening?
Certain factions in USA , UK and Israel do not want the Iranians to negotiate with IAEA
Are very much afraid of Hagel and his policies
Do not want bidden and USA to talk to Iran

All above three points will be a big step towards their demise

They will do anything to start a war with Iran. Peace with Iran will be the end of regime in Israel (not israel itself)
